Test voltage must be applied within dv/dt rating. 3. All devices will trigger at an IF value greater than or equal to the maximum IFT specification. For optimum operation over temperature and lifetime of the device, the LED should be biased with an IF that is at least 50% higher than the maximum IFT specification. The IF should not exceed the absolute maximum rating of 60 ma. Example: For MOC3052M, the minimum IF bias should be 10 ma x 150% = 15 ma 4. Isolation voltage, VISO, is an internal device dielectric breakdown rating. For this test, pins 1 and 2 are common, and pins 4, 5 and 6 are common. 4

6 APPLICATIONS INFORMATION Basic Triac Driver Circuit The random phase triac drivers MOC3051M, MOC3052M and MOC3053M can allow snubberless operations in applications where load is resistive and the external generated noise in the AC line is below its guaranteed dv/dt withstand capability. For these applications, a snubber circuit is not necessary when a noise insensitive power triac is used. Figure 7 shows the circuit diagram. The triac driver is directly connected to the triac main terminal 2 and a series resistor R which limits the current to the triac driver. Current limiting resistor R must have a minimum value which restricts the current into the driver to maximum 1 A. The power dissipation of this current limiting resistor and the triac driver is very small because the power triac carries the load current as soon as the current through driver and current limiting resistor reaches the trigger current of the power triac. The switching transition times for the driver is only one micro second and for power triacs typical four micro seconds. Triac Driver Circuit for Noisy Environments When the transient rate of rise and amplitude are expected to exceed the power triacs and triac drivers maximum ratings a snubber circuit as shown in Figure 8 is recommended. Fast transients are slowed by the R-C snubber and excessive amplitudes are clipped by the Metal Oxide Varistor MOV. Triac Driver Circuit for Extremely Noisy Environments As specified in the noise standards IEEE472 and IEC Industrial control applications do specify a maximum transient noise dv/dt and peak voltage which is superimposed onto the AC line voltage. In order to pass this environment noise test a modified snubber network as shown in Figure 9 is recommended. LED Trigger Current versus Temperature Recommended operating LED control current I F lies between the guaranteed I FT and absolute maximum I F. Figure 3 shows the increase of the trigger current when the device is expected to operate at an ambient temperature below 25 C. Multiply the datasheet guaranteed I FT with the normalized I FT shown on this graph and an allowance for LED degradation over time. Example: I FT = 10 ma, LED degradation factor = 20% I F at -40 C = 10 ma x 1.25 x 120% = 15 ma LED Trigger Current vs. Pulse Width Random phase triac drivers are designed to be phase controllable. They may be triggered at any phase angle within the AC sine wave. Phase control may be accomplished by an AC line zero cross detector and a variable pulse delay generator which is synchronized to the zero cross detector. The same task can be accomplished by a microprocessor which is synchronized to the AC zero crossing. The phase controlled trigger current may be a very short pulse which saves energy delivered to the input LED. LED trigger pulse currents shorter than 100 µs must have increased amplitude as shown on Figure 4. This graph shows the dependency of the trigger current I FT versus the pulse width. I FT in this graph is normalized in respect to the minimum specified I FT for static condition, which is specified in the device characteristic. The normalized I FT has to be multiplied with the devices guaranteed static trigger current. Example: I FT = 10 ma, Trigger PW = 4 µs I F (pulsed) = 10 ma x 3 = 30 ma Minimum LED Off Time in Phase Control Applications In phase control applications, one intends to be able to control each AC sine half wave from 0 to 180. Turn on at 0 means full power and turn on at 180 means zero power. This is not quite possible in reality because triac driver and triac have a fixed turn on time when activated at zero degrees. At a phase control angle close to 180 the driver s turn on pulse at the trailing edge of the AC sine wave must be limited to end 200 µs before AC zero cross as shown in Figure 10. This assures that the triac driver has time to switch off. Shorter times may cause loss of control at the following half cycle. Static dv/dt Critical rate of rise of off-state voltage or static dv/dt is a triac characteristic that rates its ability to prevent false triggering in the event of fast rising line voltage transients when it is in the off-state. When driving a discrete power triac, the triac driver optocoupler switches back to offstate once the power triac is triggered. However, during the commutation of the power triac in application where the load is inductive, both triacs are subjected to fast rising voltages. The static dv/dt rating of the triac driver optocoupler and the commutating dv/dt rating of the power triac must be taken into consideration in snubber circuit design to prevent false triggering and commutation failure. 6
